I would EASILY pay 12.5% more (that's the bit overhead) for memory that actually works.
If my data is fine being corrupted to save 12.5% on RAM costs, then why am I even bothering processing the data? Apparently it's worthless.
People today weigh the cost of maybe 16 vs 32GB on a mid-tier desktop. ~doubling the cost for twice the RAM. Yes, paying 12.5% more for ECC RAM is a no-brainer.
